The Schedule referred to in'these Letters Patent and making part of the same.

To all 'whoin t't may concern Be it known that 1, JOSHUA '1. OwEN,'of Philadelphia, Pennsylvania, have invented a new and useful Gar-Wheel; .andI do herebyldeclare that the following is a full and exact description of the same, reference being bad; to the annexed drawings, forming part hereof, and to the several letters marked thereon, in which drawings---v Figure 1 represents an interior face view of said wheel.

' Figure 3, a perspective view of the detachable hub and attached central parts of ,said wheel, looking at' the outer face thereof. v

Figure 4, a similar view of said wheel, the central part being removed. 4

Figure 5, a similar view of the keys 7:.

Figures 6 and 7 similar views of the India-rubber springs t and v Referring to the, drawings, in figsQl, 2, ,and 4, 00 represents the periphery, which is cast with the interior annular flange b, and the several grooved ribs a, forming the sockets g and h, which appear most distinctly in fig. 4.

In figs. 1, 2, and 3, d is the detachable hub and at tached solid central parts of the wheel, it beingprovided with grooves, e, in the edge, and with projections, j, which last, when the central portion of the wheel is in place, enter the sockets h, fitting said sockets loosely, as shown injjg. 1. p

t, figs. 1, 2, and 7, represent India-rubber springs,

v inserted into the sockets l), and retained there by the recessed edges of the projections f, and by the sides of the ribs 0, which are slightly under-cut or dovej, figs. 1, 2, and 6, represent Indiarrubber springs, inserted into the sockets g, and retained there by the sliding removable key-pieces k, the side edges of which '(see fig; 5) slide in the grooves in the sides of ribs 0, and the end tongues of which enter the grooves e.

This wheel is applied to the axles of cars in the ordinary'manner; and, from its peculiar construction, it acts as an adjunct to the springs usually employed in breaking the force of concussions dueto obstructions In many cases, these wheels may be employed as substitutes for the ordinary springs.

' I do not wish to confine myself to the use of Indiarubber springs, asother elastic gums might be employed, or spiral "springs might be substituted in place of the'springs t and j. 7

Having thus described my invention,

' I claim, and desire tosecure by Letters Patent A car-wheel, constructed substantially as set forth. Witnesses: JOSHUA '1. OWEN.
